StarTrade is a retro-ish space simulation game with an open world setting. You start as a money- and nameless character, only in possession of his space ship. Increasing your wealth by trading, fighting off pirates or being a pirate yourself, you slowly grow through the games universe, acquiring new equipment and ships.
The universe is fully simulated, including a "supply and demand" trading system with dynamically calculated prices and the ongoing battle between two opponent forces.
StarTrade has full mod support allowing you to change 100% of its content.
